A process for fabricating a heater cartridge assembly for use with an inductive coupling solder station, the process comprising:
- forming a solder tip having a distal end defining a soldering surface and a proximal end defining a projecting core;
- forming a heater element of a ferromagnetic material by a press punch process to shape said heater element to fit over said projecting core of said solder tip;
- brazing said heater element to said projecting core;
- installing a coil winding over said heater element;
- installing a shield over said coil winding, heater element and proximal end of said solder tip to form a solder tip assembly;
- and
- inserting said solder tip assembly into a distal end of a sleeve and connecting said coil winding to a connector assembly at a proximal end of said sleeve.
A heater cartridge assembly for use with an inductive coupling solder station, said heater cartridge assembly formed by the process comprising:
- forming a solder tip having a distal end defining a soldering surface and a proximal end defining a projecting core;
- forming a heater element of a ferromagnetic material by a press punch process to shape said heater element to fit over said projecting core of said solder tip;
- brazing said heater element to said projecting core;
- installing a coil winding over said heater element;
- installing a shield over said coil winding, heater element and proximal end of said solder tip to form a solder tip assembly;
- and
- inserting said solder tip assembly into a distal end of a sleeve and connecting said coil winding to a connector assembly at a proximal end of said sleeve.
A process for fabricating a heater cartridge assembly for use with an inductive coupling solder station, the process comprising:
- forming a solder tip from a material selected from the group consisting of cast or machined copper, sintered copper, copper alloy, silver or a silver alloy, said solder tip having a distal end defining a soldering surface and a proximal end defining a projecting core;
- forming a heater element from a sheet of iron-nickel ferromagnetic alloy material by a press punch process to shape said heater element to fit over said projecting core of said solder tip so that the thickness of the heater element is in the range of from between about 0.05 mm and 0.15 mm;
- heat treating said heater element in a hydrogen atmosphere oven;
- brazing said heater element to said projecting core;
- installing a coil winding over said heater element, said coil winding having between 13.5 to 18.5 turns in two layers formed from an insulated silver, copper or nickel plated copper wire having a diameter between about 0.15 mm and 0.25 mm;
- installing a shield over said coil winding, heater element and proximal end of said solder tip to form a solder tip assembly;
- and
- inserting said solder tip assembly into a distal end of a sleeve and connecting said coil winding to a connector assembly at a proximal end of said sleeve.
